Species Information
Size	30mm or 1.2" SL. Find near, nearer or same sized spp.
Identification	Minute species of Catfish, usually actively swimming in the water column, at other times resting on plants or substrate. Tiny barbels visible on close examination (particularly when feeding). Body is remarkably transparent, the organs are enclosed in a silvery sac, although the stomach contents and other areas of the alimentary tract may be visible. There are two dark pigment spots on the body, one in the humeral area, the other on the caudal peduncle (this spot actually appear to be made up of pigmented skeletal elements as opposed to epidermal pigment).
Sexing	Unknown, although females may show ovaries through body wall when gravid.
General Remarks	One of the photographed specimens originated in a shipment of Corydoras pygmaeus from Peru.

Husbandry Information
Feeding	Small Live Crustaceans, Worms, Insect Larvae taken eagerly. Dry food ignored. Incipient parasitism. User data.
Furniture	Not important. Sand or bare base probably best.
Compatibility	Complex and variable. No problems with small characins, but there is some evidence that they are opportunistically lepidophagous on slightly larger fish under some circumstances. It has been observed that they will attack large ultra peaceful fish e.g. Doradids. There are no intraspecific compatibility problems observed, a larger group needs to be assembled to gather more information.
